Abstract:

A pathological study was conducted on poultry diseases occurring at Sylhet district of Bangladesh during the period from March 2015 to February 2016 to know the disease pattern of poultry. A total of 1351 birds either sick or dead were studied in Field Disease Investigation Laboratory (FDIL), Sylhet and a total of 143 birds either sick or dead were examined at Upazilla veterinary hospital, Jaintapur. The diagnosis of different diseases were performed on the basis of history of the affected flock, visual examinations, post mortem examinations, pathological findings, isolation and identification of the causal agents, serology and age of affected birds. Cases found in FDIL were Newcastle disease (9.85 %), Infectious bursal disease (16.43 %), colibacillosis (14.51 %), omphalitis (10.14 %), salmonellosis (7.32 %), fowl cholera (3.11 %), aspergillosis (7.33 %), duck plague (9.16 %) and duck cholera (7.03 %). Disease prevalence was recorded as 38.04 % among the age group of >2 – 8 weeks followed by 28.24 % among 0 – 2 weeks of age, 6.66% among >8 – 20 weeks of age and 3.39 % among >20 weeks of age. It was found that prevalence of poultry diseases were significantly highest in summer season (47.36 %) followed by rainy season (25.4 %) and winter (24.02 %). Cases found in Upazilla veterinary hospital, Jaintapur were newcastle diseases (19.58%), coccidiosis (16.79 %), duck plague (15.39 %), infectious bursal diseases (14.68 %), Non- specific pneumonia (10.49 %), non-specific enteritis (7.69 %), duck cholera (5.59 %), helminthiasis (4.19 %), nutritional deficiency (3.50 %) and aspergillosis (2.10 %). Age-wise disease prevalence was recorded as 6.26 % for 0 – 2 weeks, 66.38 % for >2 – 8 weeks, 20.22 % for >8 – 20 weeks and 6.96 % for >20 weeks. Prevalence of poultry diseases were significantly higher in summer (40.5 %) followed by rainy season (32.11 %) and winter (27.2 %). The study may help to know the prevalence of poultry diseases for the improvement of poultry production in Sylhet region.
